feat: add templating utils method dynamically; method to set http code Added new utils.set_http_response(integer) to set the HTML response code from a template. Useful for error handling inside template. Also noted that a real TemplatingUtils (like set_http_response) method gets the TemplatingUtils object instance, but there is no way to do this with registerUtil() from an extension file. Added new instance.registerUtilMethod() method to register a function in an extension as a method passing the client instance in as the first parameter (aka self).
